Answer:
Step-by-step explanation:
9³
= 9 × 9 × 9
= 81 × 9
= 729
(-7)²
= -7 × (-7)
= 7 × 7
= 49
(-2)⁴
= -2 × (-2) × (-2) × (-2)
= 2 × 2 × 2 × 2
= 2² × 2²
= 4 × 4
= 16
(⅚)³
= ⅚ × ⅚ × ⅚
[tex] \sf = \frac{ {5}^{3} }{ {6}^{3} } [/tex]
[tex] \sf = \frac{125}{36} [/tex]
[tex] \sf = 3 \frac{17}{36} [/tex]
(-⅔)⁴
= -⅔ × (-⅔) × (-⅔) × (-⅔)
[tex] \sf = \frac{ {2}^{4} }{ {3}^{4} } [/tex]
[tex] \sf = \frac{16}{81} [/tex]
1.2²
= 1.2 × 1.2
= 1.44
1⁸
= 1 × 1 × 1 × 1 × 1 × 1 × 1 × 1
= 1
(-5)⁵⁵
= (-5) × (-5) × .... × (-5)
= -277.555.756.156.289.135.105.907.917.022.705.078.125
0.5³
= 0.5 × 0.5 × 0.5
= 0.25 × 0.5
= 0.125
Conclusion:
